New description:

 As described here:
 http://thread.gmane.org/gmane.comp.search.xapian.general/5740/focus=5743

 If the spelling correction algorithm considered frequency and edit-
 distance
 (using  some reasonable heuristic) we would see dramatically better
 results.
 ~~The current spelling algorithm will only correct words that never appear
 in the
 spelling index.~~ ''(Since 1.2.3, it will offer a correction for a word
 when the correction has a higher frequency than the word)''
